It now turns out that the culprit, at one point, worked for…The Intercept.

On Friday, a Missouri man named Juan Thompson was arrested for making multiple threats to JCCs across the country in order to harass his ex-girlfriend. Thompson is suspected of being a copycat – of hearing about the JCC phone calls and then conducting his own campaign of phone terrorism.

According to the FBI, Thompson dated a Jewish woman; after their relationship ended, he sent defamatory emails and faxes to the woman’s employer. He then stalked her. After that, he made “at least eight JCC Threats nationwide as part of his campaign” against his ex-girlfriend. He then tried to blame the woman in order to have her prosecuted; he tweeted, “Know any good lawyers? Need to stop this nasty/racist #whitegirl I dated who sent a bomb threat in my name & wants me to be raped in jail.”

Here’s what we know about Thompson: he’s a left-wing reporter who made up material while working at The Intercept. He was fired in February 2016 for fabricating quotes in his stories and creating “fake email accounts that he used to impersonate people,” one of which was a Gmail account in the name of the editor-in-chief of that publication.

He says he “voted for Bernie Sanders.” Thompson, who is black, tweeted just weeks ago that Trump was attempting to “remove black ppl from the southside of Chicago.”
